Product Review

I like this series of gel pens. I have all 4 nib sizes. The nib, some say, is
fragile but I don't believe that is the case, at least not in my experience. I
don't have to press hard to get them to make a mark so I am less likely to break
the nibs than someone with a heavy hand. If you treat these pens right they
perform just fine.
The 0.25mm nib of course makes the finest line and the 0.5mm the widest.
However, and it should come as no surprise, the smaller the nib the "rougher"
the pen feels when writing with it. However the nibs being smaller in diameter
than other pens their nib size they make for excellent drafting/drawing pens
when you use a straight edge such as a triangle or ruler. Again one does not
have to press hard to get these pens to produce a line.
The ink in these pens is dark and the pens write without skipping or the ink
running out unevenly. The ink supply is typical of such pens, maybe a tad more
generous. The clear plastic barrels have a ribbed surface for grasping near the
nib. The are as comfortable as any plastic barreled pen or pencil. The only
thing that could make these pens any better is to make the retractable.
